Denso OE Manufactured TPMS Sensor 550-3014

Denso TPMS Sensor 550-3014 is a direct tire pressure monitoring system sensor built for vehicle-specific TPMS operation. It is designed for 315 MHz applications and uses a clamp-in mounting style for confirmed fitment on select INFINITI models.

For drivers servicing an INFINITI Q50 or INFINITI QX50, this OE Manufactured sensor supports direct pressure monitoring and preserves vehicle system functions, including fill assist and auto locate.

Key Features

• Direct TPMS sensor with real-time pressure signal transmission
• Electric power source for vehicle system integration
• Clamp-in mounting method for OE-style installation
• Mounting hardware included
• Gasket or seal included
• Designed to preserve diagnostic trouble codes and system functions
• Built for 315 MHz applications listed in the fitment data

Detailed Description

The Denso 550-3014 TPMS sensor is an OE Manufactured replacement for vehicles that use a direct tire pressure monitoring system. It is engineered to work with the vehicle’s TPMS architecture while maintaining functions such as fill assist, auto locate, and diagnostic trouble code retention. This makes it a practical choice for service work where the original system behavior needs to remain intact.

Fitment includes 2014-2015 INFINITI Q50 and 2014 INFINITI QX50. This part cross-references Infiniti 407004GA0A for the same application. The Denso 550-3014 is a focused replacement for INFINITI TPMS service where a clamp-in, 315 MHz sensor is specified.

What It Helps Solve

• TPMS warning light caused by a failed sensor
• Inaccurate tire pressure readings from a worn sensor
• Loss of direct pressure signal transmission
• System faults after tire service or sensor replacement
• Diagnostic trouble codes related to TPMS sensor failure

Installation Notes and Tips

After installation, the vehicle may require a TPMS relearn procedure according to the manufacturer’s service process. Denso notes that some do-it-yourself installations still need a trusted repair shop to complete relearn steps. Verify 315 MHz specification, clamp-in design, and vehicle fitment before service on the INFINITI Q50 or INFINITI QX50.

Quality Assurance

Denso OE Manufactured parts are built to match the vehicle system requirements listed in the application data. This sensor is intended to preserve original TPMS functions and maintain diagnostic trouble code capability during service replacement.
